植物硫同位素与大气环境变化

Sulfur Isotope in Plants and Atmospheric Environmental Change

硫是植物生长必需的营养元素之一,也是一种大气污染物。植物中硫同位素能够提供植物吸收大气硫化物以及硫在植物中新陈代谢的重要信息,在监测陆地生物圈的短期和长期的环境变化中有着十分重要的作用。借助硫同位素的手段可以阐明陆生生态系统发生的环境变化及其历史趋势,植物硫同位素已经成为研究和解析区域环境大气硫污染来源和迁移机制的独特而又有力的工具。

The sulfur is not merely one kind of air pollutant, but also is the plant growth essential nutritive elements. Sulfur isotope in plants can provide important information about the plants to absorb atmospheric sulfides as well as the metabolism of sulfur in plants. It plays an extremely important role in monitoring the short-term and long-term environmental change of the terrestrial biosphere. With the aid of the information of sulfur isotope, it can clarify the environmental change and its historical trend of the terrestrial ecosystem. Sulfur isotope in plants has already become a unique and powerful tool to study and analyze the sources and migration mechanisms of atmospheric sulfur pollution in the regional environment.
